2002-10-12Fix for bug #795: two clauses that seem redundant are not really, ifTom Lane
one is pushed down into an outer join and the other is not.
2002-10-11Oops, back out newNode changes. We are not ready for that yet.Bruce Momjian
2002-10-11Prevent tv_sec from becoming negative in connection timeout code.Bruce Momjian
2002-10-09Lock on the rule relation wasn't removed after adding the comment.Bruce Momjian
Added Tom's patch fix for heap_close. Rod Taylor

They're also linked into the > postmaster. I don't see anything unusual. Attached is a patch to fix the mb linking problems on AIX. As a nice side effect it reduces the duplicate symbol warnings to linking libpq.so and libecpg.so (all shlibs that are not postmaster loadable modules). Please apply to current (only affects AIX). The _LARGE_FILES problem is unfortunately still open, unless Peter has fixed it per his recent idea. Zeugswetter Andreas SB SD
2002-10-09Have SET not start transaction when autocommit off, with doc updates.Bruce Momjian
2002-10-08Move responsibility for setting QuerySnapshot for utility statementsTom Lane
into postgres.c; make sure it happens for all cases that seem to need it. Perhaps it would be better to explicitly exclude just a few utility statement types from setting a snapshot?
2002-10-07Change order of operations during XLogFlush so that we try to includeTom Lane
in our write/flush operation any WAL entries that got queued while we were waiting to get the WALWriteLock. This improves throughput when transactions are small enough that several can be committed per WAL write (ie, per disk revolution).
2002-10-06Clarify comment.Bruce Momjian
2002-10-04Restrict CREATE OPERATOR CLASS to superusers, per discussion some weeksTom Lane
ago.
2002-10-04Require superuser privilege to create a binary-compatible cast, perTom Lane
discussion some weeks ago. Also, add a check that two types to be binary-equivalenced match as to typlen, typbyval, and typalign; if they don't then it's surely a mistake to equivalence them.
2002-10-04Fix a couple of grammatical errors in error messages.Tom Lane
2002-10-04Tweak a few of the most heavily used function call points to zero outTom Lane
just the significant fields of FunctionCallInfoData, rather than MemSet'ing the whole struct to zero. Unused positions in the arg[] array will thereby contain garbage rather than zeroes. This buys back some of the performance hit from increasing FUNC_MAX_ARGS. Also tweak tuplesort.c code for more speed by marking some routines 'inline'. All together these changes speed up simple sorts, like count(distinct int4column), by about 25% on a P4 running RH Linux 7.2.
2002-10-03Hack to make it possible to load CREATE CONSTRAINT TRIGGER commands thatTom Lane
are missing the FROM clause (due to a long-ago pg_dump bug). Patch by Stephan Szabo, minor tweaking by Tom Lane.
2002-10-03In a bootstrap process or standalone backend, set MaxBackends = 1Tom Lane
to avoid unnecessary consumption of semaphores.
2002-10-03Avoid palloc(0) when MaxBackends = 1.Tom Lane
2002-10-03Add SSL documentation info to README.SSLBruce Momjian
2002-10-03The attached patch fixes a number of issues related to compiling theBruce Momjian
client utilities (libpq.dll and psql.exe) for win32 (missing defines, adjustments to includes, pedantic casting, non-existent functions) per: http://developer.postgresql.org/docs/postgres/install-win32.html. It compiles cleanly under Windows 2000 using Visual Studio .net. Also compiles clean and passes all regression tests (regular and contrib) under Linux. In addition to a review by the usual suspects, it would be very desirable for someone well versed in the peculiarities of win32 to take a look. Joe Conway
2002-10-03This patch removes two unused global variables from globals.cBruce Momjian

2002-10-02Alter scale selection for NUMERIC division and transcendental functionsTom Lane
so that precision of result is always at least as good as you'd get from float8 arithmetic (ie, always at least 16 digits of accuracy). Per pg_hackers discussion a few days ago.
2002-10-02Turn GUC log_min_error_statement off by default by setting it to PANIC.Bruce Momjian
2002-10-01Pass less-unsafe parameters to Darwin's NSLinkModule. While this change ↵Tom Lane
prevents a backend coredump when loading a broken shlib, it also seems to suppress the error messages that might help debug the problem :-(. Perhaps someone would like to supply a 'linkEdit' hook to get the best of both worlds. But in the meantime, backend crash trumps error reporting.
2002-09-29Add Bear's SSL comments.Bruce Momjian
2002-09-28Make the world at least somewhat safe for zero-column tables, andTom Lane
remove the special case in ALTER DROP COLUMN to prohibit dropping a table's last column.
2002-09-27ARGH!Tom Lane
Vacuum must not advance pg_database.datvacuumxid nor truncate CLOG unless it's processed *all* tables in the database. Vacuums run by unprivileged users don't count. (Beats head against nearest convenient wall...)
2002-09-27Use heap_formtuple not heap_addheader to construct pg_index tuples.Tom Lane
heap_addheader is wrong because it doesn't cope with varlena fields, notably indpred.
2002-09-27Don't mess with HEAP_XMAX_INVALID in heaptuple.c routines; there isTom Lane
no reason to worry about the tuple commit status bits until the tuple is inserted in a relation by heapam.c. Also, improve comments for heap_addheader().
2002-09-27Have -d5 -d0 not affect the extra variables set with -d5.Bruce Momjian
2002-09-27Make postgres -d0 set server_min_messages to notice. Reset doesn't workBruce Momjian
at this area in the code.
2002-09-26Ensure that before truncating CLOG, we force a checkpoint even if noTom Lane
recent WAL activity has occurred. Without this, it's possible that a later crash might leave tuples on disk with un-updated commit status bits.
2002-09-26Fix problems with loss of tuple commit status bits during WAL redo ofTom Lane
VACUUM FULL tuple moves. Store full-width t_infomask in WAL, rather than storing low 8 bits and expecting to be able to reconstruct upper bits. While at it, remove redundant t_oid field from WAL headers (the OID, if present, is now recorded in the data portion of the tuple). WAL version number bumped --- this does not force an initdb, you can instead run pg_resetxlog after a clean shutdown of the old postmaster.
2002-09-26This patch removes a use of uninitialized memory in lmgr/lock.c, byBruce Momjian
adding a missing sprintf(). Neil Conway
2002-09-26Pass postmaster -d down to the postgres backend to trigger special -dBruce Momjian
handling in the backend.
2002-09-26Allow SSL to work withouth client-side certificate infrastructure.Bruce Momjian
2002-09-25Remove ShutdownBufferPoolAccess exit callback, and do the work inTom Lane
ProcKill instead, where we still have a PGPROC with which to wait on LWLocks. This fixes 'can't wait without a PROC structure' failures occasionally seen during backend shutdown (I'm surprised they weren't more frequent, actually). Add an Assert() to LWLockAcquire to help catch any similar mistakes in future. Fix failure to update MyProcPid for standalone backends and pgstat processes.
2002-09-24Change default privileges for languages and functions to be PUBLIC USAGETom Lane
and PUBLIC EXECUTE, respectively. Per discussion about easing updates from prior versions.
2002-09-24Tweak conversion names to follow the established naming scheme, andPeter Eisentraut
document that scheme.
2002-09-24Add missing correction of sublevelsup when pulling up a subquery.Tom Lane
Fixes problem with cases like SELECT * FROM foo t WHERE NOT EXISTS (SELECT remoteid FROM (SELECT f1 as remoteid FROM foo WHERE f1 = t.f1) AS t1)
2002-09-23Further thinking about heap_mark4update: in HeapTupleSelfUpdated case,Tom Lane
executor should not return the tuple as successfully marked, because in fact it's been deleted. Not clear that this case has ever been seen in practice (I think you'd have to write a SELECT FOR UPDATE that calls a function that deletes some row the SELECT will visit later...) but we should be consistent. Also add comments to several other places that got it right but didn't explain what they were doing.
2002-09-23Disallow VACUUM, ANALYZE, TRUNCATE on temp tables belonging to otherTom Lane
backends. Given that temp tables now store data locally in the local buffer manager, these things are not going to work safely.
2002-09-23Get rid of bogus use of heap_mark4update in reindex operations (cf.Tom Lane
recent bug report). Fix processing of nailed-in-cache indexes; it appears that REINDEX DATABASE has been broken for months :-(.
2002-09-22In UpdateStats(), don't bother to update the pg_class row if it alreadyTom Lane
contains the correct statistics. This is a partial solution for the problem of allowing concurrent CREATE INDEX commands: unless they commit at nearly the same instant, the second one will see the first one's pg_class updates as committed, and won't try to update again, thus avoiding the 'tuple concurrently updated' failure.
2002-09-22Remove commas from %type and %token lists, for compatibility with newerTom Lane
versions of bison.
2002-09-22Translation updates, some messages tweaked.Peter Eisentraut
2002-09-22RelationClearRelation must reset rd_targblock and update rd_nblocksTom Lane
even when dealing with a nailed-in-cache relation; otherwise, following VACUUM truncation of a system catalog, other backends might have unreasonably large values of these fields.
2002-09-22server_min_messages and friends should have valid values at bootup.Tom Lane
2002-09-22Replace pg_attribute.attisinherited with attislocal and attinhcountTom Lane
columns, to allow more correct behavior in multiple-inheritance cases. Patch by Alvaro Herrera, review by Tom Lane.
2002-09-22Bring SIMILAR TO and SUBSTRING into some semblance of conformance withTom Lane
the SQL99 standard. (I'm not sure that the character-class features are quite right, but that can be fixed later.) Document SQL99 and POSIX regexps as being different features; provide variants of SUBSTRING for each.
2002-09-22Move most of the error checking for foreign-key constraints out ofTom Lane
parse analysis and into the execution code (in tablecmds.c). This eliminates a lot of unreasonably complex code that needed to have two or more execution paths in case it was dealing with a not-yet-created table column vs. an already-existing one. The execution code is always dealing with already-created tables and so needs only one case. This also eliminates some potential race conditions (the table wasn't locked between parse analysis and execution), makes it easy to fix the gripe about wrong referenced-column names generating a misleading error message, and lets us easily add a dependency from the foreign-key constraint to the unique index that it requires the referenced table to have. (Cf. complaint from Kris Jurka 12-Sep-2002 on pgsql-bugs.) Also, third try at building a deletion mechanism that is not sensitive to the order in which pg_depend entries are visited. Adding the above- mentioned dependency exposed the folly of what dependency.c had been doing: it failed for cases where B depends on C while both auto-depend on A. Dropping A should succeed in this case, but was failing if C happened to be visited before B. It appears the only solution is two separate walks over the dependency tree.
2002-09-21Add last-ditch defense against attempts to compile datetime code withTom Lane
